Hi!

My PC sometimes get lag spikes because of ntoskrnl.exe is causing much of my CPU.

It sometimes spikes to about 20-90 % and it happens randomly. Not just playing games, but also when doing nothing in Windows.

It stays like this for a second or so and goes back Down to below 1 %.

I have tried to format my pc and update my drivers, but nothing seems to work.

    ntoskrnl.exe does scan your computer's cache and finds available driver updates on the Internet. Can you tell us if this background process is harming your computer? And how long does it take much memory and CPU usage every time you use your computer? Did you receive any error messages when it's running?

    We're looking forward to your response.

    At this time, we recommend performing a full system scan for your computer to see if there are unwanted programs and script that slowdown your computer's performance. To do this, follow the steps below to start scanning your computer by using Windows Defender:

    1. Press Windows + S to open Search Box.
    2. Type Windows Defender, then click it.
    3. In Home tab, select Full under Scan options.
    4. Click Scan now to begin the thorough scanning of your computer.
    5. Wait for the process to finish.
    6. If there are any findings, send us the results through screenshot.
    7. Before closing the application, make sure that Windows Defender is always turned on.

    In addition, you can set a schedule for Windows Defender to perform periodic scans for your PC. Visit this link for more information about how to set scan schedules.
